Introduction of PPGI
Pre-Painted Galvanized Steel (PPGI) – Durability Meets Aesthetics.PPGI is a high-performance steel product featuring a galvanized base coated with premium paint finishes through a continuous coil-coating process. Combining corrosion resistance from the zinc layer with vibrant colors and superior weatherability, PPGI is ideal for construction (roofing, wall cladding), appliances, automotive parts, and decorative applications.
Key Advantages:
- Corrosion Resistance** – Dual protection from galvanization and painted layers.
- Aesthetic Flexibility** – Wide color options & gloss/matte finishes.
- Eco-Friendly** – Solvent-free coatings comply with environmental standards.
- Cost-Effective** – Low maintenance & long service life reduce lifecycle costs.
Available in customized thicknesses, widths, and coatings (PVDF, HDP, polyester), our PPGI ensures durability and visual appeal for diverse industries.
